Also known as roll, tension, split, and expansion pins, these pins have a slot that presses closed when the pins are inserted so they don't flex after installation. Use them for fastening, pivoting, and holding. Squeeze pins closed and install them in a hole slightly smaller than the pin. Tension holds them tight against the hole wall. At least one end is chamfered to aid insertion. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Manufactured from 420 Series Martensitic Stainless Steel. 420 is a stainless alloy that has a higher hardness than 18-8 Stainless Steel but is less corrosion resistant and will be magnetic. Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.
